27 x 40 Inches to Pixels
27 × 40 inches is 8,100 × 12,000 pixels at 300 DPI, 4,050 × 6,000 pixels at 150 DPI and 2,592 × 3,840 pixels at the 96 PPI screen standard.

27 × 40 inches in pixels at every common resolution
The pixel count changes with the resolution you are working to — these are the values you are most likely to need.
| Resolution | Width × height in pixels | Typical use |
|---|---|---|
| 72 DPI | 1,944 × 2,880 | Legacy web |
| 96 DPI | 2,592 × 3,840 | Screen and CSS |
| 150 DPI | 4,050 × 6,000 | Posters and drafts |
| 300 DPI | 8,100 × 12,000 | Photo and magazine print |
| 600 DPI | 16,200 × 24,000 | Fine art and line work |
How the conversion works
Pixels are found by multiplying the length in inches by the pixel density: pixels = inches × DPI. For 27 × 40 inches at 300 DPI that is 27 × 300 = 8,100 and 40 × 300 = 12,000.
27 × 40 inches is the US one-sheet, the standard cinema poster.
It is the size that fits a lobby lightbox, which is why 27 × 40 frames are sold everywhere — though one-sheets printed before the 1980s were an inch taller, at 27 × 41.
Hung and read from about a metre away, 150 to 200 DPI is indistinguishable from 300, so 4,050 × 6,000 pixels is usually all it needs rather than the 8,100 × 12,000 a 300 DPI file would carry.
That works out at 97.2 megapixels at 300 DPI, or 24.3 megapixels at 150 DPI. In metric the same size is 68.58 × 101.6 cm.
Frequently asked questions
How many pixels is 27 × 40 inches, the US one-sheet?
8,100 × 12,000 pixels at 300 DPI, 4,050 × 6,000 at 150 DPI and 2,592 × 3,840 at the 96 PPI screen standard. Multiply the inches by whichever density you are working to.
How many pixels is 27 × 40 inches at 300 DPI?
8,100 × 12,000 pixels. That is the standard density for photographic and magazine printing.
What is 27 × 40 inches in centimetres?
68.58 × 101.6 cm, because one inch is exactly 2.54 centimetres.
Does this size really need 300 DPI?
Usually not. Something this size is read from about a metre away, and at that distance 150 to 200 DPI is indistinguishable from 300. That is 4,050 × 6,000 pixels rather than 8,100 × 12,000 — a quarter of the file for no visible loss.
Why does the pixel count change with DPI?
A pixel has no fixed physical size. The DPI value says how many pixels fill one inch, so raising it raises the pixel count needed to cover the same physical space.
